PNNL team develops new low-cost method to convert captured CO2 to methane

Green Car Congress

Researchers at the Department of Energy’s Pacific Northwest National Laboratory have developed a new method to convert captured CO 2 into methane, the primary component of natural gas. Conventionally, plant operators can capture CO 2 by using special solvents that douse flue gas before it’s emitted from plant chimneys. Heldebrant, D.,

Harvard team demonstrates new metal-free organic–inorganic aqueous flow battery; potential breakthrough for low-cost grid-scale storage

Green Car Congress

Wide-scale utilization of flow batteries is, however, limited by the abundance and cost of these materials, particularly those using redox-active metals and precious-metal electrocatalysts. But until now, flow batteries have relied on chemicals that are expensive or hard to maintain, driving up the cost of storing energy. Background.

GWU team demonstrates highly scalable, low-cost process for making carbon nanotube wools directly from CO2

Green Car Congress

This synthesis consumes only CO 2 and electricity, and is constrained only by the cost of electricity. The process is constrained by the (low) cost of electricity. Carbon dioxide is the sole reactant in this CNT transformation, providing a financial impetus for the removal of this greenhouse gas. —Johnson et al.

Lux Research: fuel cell vehicles lag other drivetrains in terms of cost of ownership; ICE and HEV lowest cost

Green Car Congress

Based on an analysis of various cost of ownership scenarios for various drivetrains, including internal combustion engine (ICE) gasoline and diesel; hybrid (HEV); battery-electric (EV); plug-in hybrid electric (PHEV); and fuel cell vehicles, Lux Research concludes that fuel cell vehicles (FCVs) are “ solidly in a laggard position. ”.
